It's quite easy if you just use your noggin

Asylum seekers are not allowed to work, so are reliant on reduced benefits and social housing (different allocation of social housing to natives, so no worry about them jumping ahead of any British workshy scrotes now, so don't fret). Why aren't they allowed to work I hear any sensible person ask?
Well, you see, a load of racist anti-immigrant bigots went "waaa waaa waaa they're just claiming to be asylum seekers to take all our jobs, the low paid ones which Brits like us don't want to do" so the governmnet, in true Tabloid Policy style, denied asylum seekers the right to work, so any doctors, nurses, teachers etc who are qualified to work in the UK, just can't. So, because they can't work, there's this little thing called duty of care, you may have heard about it, it's sometimes considered part of what's being British, and basically it means that being decent human beings (we are decent human beings aren't we? Well, I am) we look after people in need whenever we can. So rather than your asylum seeker being able to work, pay rent, tax, food etc, they now are reliant on the state to support them. Course, then all the right wing racist biggots said "Waa waa waa they're all coming over to get benefits that our own workshy scrotes should get" so the benefits that an asylum seeker get are lower than what a British workshy scrote would get.
Then the right wing racist biggots said "Waa waa waa they're still coming for benefits, and 0.5% of the total benefit expendature is way too high, that money should go to British workshy scrotes" and we have the situation we're in today where the media loves blurring the line between immigrant and asylum seeker.
Great isn't it?
So Catholics who send their kids to Catholic schools aren't native then?
Or Anglicans who send their children to CoE schools?
Educating someone who spent most of their childhood speaking another language costs more in time, but even if English isn't spoken at home, most children who were born here are able to speak english by the time they reach primary school (the exception I know of being the son of an ex-neighbour, who could hardly speak, didn't know his colours or how to count to 3, but could swear like a trooper. Course his mother was white, english (native), and never did a days work in her life, oh and her other kids are currently helping to boost the prison population even higher).
